This invention construction. j j

A prime desideratum is to provide an apparatus of this kind which isparticularly applicable to a brick drier or the like to generallysimplify, render more eflicient and reduce the cost of operationof-thesame.

Specifically' an aim is toy provide a structure of this type in unitscapable of use singly or in a battery, devoid of fluestherethrough,'whereby special front or rear ends are unnecessary, beformed by a continuation of the masonry of the firebox, and the spacearched by the unit or units may ycommunicate directly or with thedischarge flue for the firebox.

Additional objects and advantages will become apparent if not laterspecifically mentioned, from a consideration of the descriptionfollowing taken in connection with accompanying drawings illustrating anoperative embodiment.

In said drawings Figure 1 is a view of the apparatus in front elevation,but partially installed to disclose details; l

Figure 2 is a plan of one of the drier units, partly broken away and insection;

Figure 3 is a side elevation of one of the drier units, and

Figure 4; is a perspective view suggesting a battery of the drier unitsconnected in operative relation.

Referring specifically to the drawings, wherein like referencecharacters designate like or similar parts, drier units are shown at 10and each unit is designed so that it may be made in a single metalliccasting. Each unit 10 is similar, of arch shape as shown in that itcomprises spaced parallel arched walls of substantially equal lengthjoined at their edges by end and bottom walls, has an interiorlyunobstructed water space, attaching lugs 11 integral with the unit, aplurality of openings 12 through the end walls thereof and an opening 13through the top.

011e or more units 10 may be used in an installation. When one unit isemployed, openings or apertures 12 at both end walls have suitable plugsor closures 14 screwed or otherwise fastened therein, as shown inFigures 2 and 3. Vater is supplied to the unit or units as through apipe a connected in one of the lowermost plugs 414 at the front oftheunit and the return line b for relates to a `steam drier so that thefront wall .may

condensation is connected at the opposite end inthe adjacent lowermostplugs 11i. A pipe 15 isscrewed into the opening 13 through .which steamunder appropriate control may be taken from the unit. Said pipe 15 mayextend to coils or'the like in i t A rier ltunnels for dryingpurposes.VV Obviously the unit, as in Figure 1, may be equipped withaccessories such as steam or pressuregage 16, and a water. gagel?arranged in communication with the water space of the unit by pipes 18.

Said unit 10 isused in connection with a furnace 19 as in Figure 1.Furnace 19 has upright walls of masonry at 2O on which the section 10rests and to which it is cemented and anchored, as by means of bolts 21passed through the lugs 11. As a result, the unit crowns the combustionchamber or Firebox` 22. The fuel door of said furnace is shown at 23 andbelow the same is an ash-pit door 24E. The front wall 20 covers theentire frontpof unit 10 and the i products of combustion from thefurnace discharge from the combustion chamber directly into a chimney orsmoke flue to which the unit is directly fastened and anchored` bycement and the aforesaid bolts 21.

The unit is arranged under a drying tunnel in a kiln so that the bricksplaced therein, usually on trucks, will be subjected tothe drying actionof the heat radiating from V the drier unit through generation of steamin the latter when fire is maintained in furnace 19. Preferably a steampressure of twenty-live pounds is maintained in the unit 10.

About the openings 12 and 18, each unit is preferably reinforced bybosses 26 and 27.

Said units 10 may be used in battery form instead of singly. Referringto Figure 4,

in this connection, three units 10 have been so shown although thenumber employed is optional. These units 10 are mounted in a furnace 19similarly to the single unit. In the present instance, openings 12 ofthe facing ends of the units are not plugged but remain open and alined,and the units are clampedy together water-tight by bolts 28 passedthrough adjacent ears 11. Plugs 14` are used for the openings 12 only atthe free end walls of the outer units branch pipes 29 (in lieu of pipe15) are detachably threadedy into the openings 13 and in turn threadedto a pipe functions similarly to the pipe l5.

bolts may also be used in the front and rear series of lugs Il to engagethe front wall oi the 'furnace and the chimney.

In both arrangements, a fire in the fur,- nace 19 causes steam to 'begenerated within the units IO, due to the presence of water suppliedthrough pipes into plugs Ill in rear end of section, say, twenty-fivepounds pressure.` The heat ra.- diating 'from the units is imparted toand dries the bricks or other ,materials in the 'associated dryingtunnel or the like through Allproducts oi combustion pass directly fromthe chamber or In both arrangements, the bolts and pipe connections arereadily displaceable to enable re- Inoval, substitution or repair of aunit.

v Various changes may be resorted to within the spirit and scope of theinvention as defined by appended Claims. o
